NEXT MEETING: Wednesday, April 16, 2025, 6:00 PM at 2045 Memory Lane in Silver City, New Mexico. The GCAS's next monthly IN-PERSON ONLY meeting features speaker geoarchaeologist Dave Rachal PhD of Tierra Vieja Consulting in Las Cruces NM. Doors open at 6:00 PM with light refreshments on offer. Socializing and a brief-to-nonexistent business meeting will immediately precede Dave's presentation of: How Did The Seeds Get There? Ruppia cirrhosa Ecology, Depositional Context and Accurate Radiocarbon Dating at White Sands: "The stratigraphic and geomorphic contexts, and ultimately the chronometric determinations, at White Sands Locality-2 (WHSA-2) are topics of controversy that stem from conflicting interpretations of the processes that deposited the Ruppia cirrhosa (Ruppia) seeds within the paleo-Lake Otero footprint site....[O]ur interpretation depicts the shoreline as an unstable, dynamic lake margin to which Ruppia seeds...were transported from deep-water, offshore growth beds during storm events and deposited on the lake shore in seed balls. These unusual aggregates, known to mix seeds of wide-ranging ages, were gradually broken apart by several cycles of wave action and erosion and redeposited in layers....[W]e will delve into both the ecology and the depositional context of Ruppia and discuss why the Ruppia seeds at paleo-Lake Otero are problematic materials for radiocarbon dating." Check out Dave's and Tierra Vieja Consulting's YouTube videos (links are on our Events page) and bring your questions for him!

Congratulations, Greg Conlin!

2019-04-27 MM ASNM - Greg Conlin Bice AwardOn April 27, 2019, the Archaeological Society of New Mexico (ASNM) formally presented four individuals, including the GCAS's favorite Field Trip Coordinator, Greg Conlin, with the Richard A. Bice Achievement Award. This annual award recognizes individuals who have made significant and sustained contributions to advance the purpose of their local archaeological society/organization and the ASNM's goals of documenting, preserving and protecting the archaeological heritage of New Mexico. Nominees do not have to be professional archaeologists, but their achievements and dedication certainly stand out.

In Greg's case, for many years he has been an active member, officer, and Board member of the GCAS. He currently plans and leads our monthly field trips; people may not realize that he actually takes two field trips for every one of ours. He performs reconnaissance of each site shortly before the field trip actually takes place, in order to confirm that our group receives accurate and current road and trail conditions. In addition to all those extra miles, Greg has devoted many years to the New Mexico SiteWatch program, monitoring multiple sites as a Site Steward. Greg joins at least nine other GCAS members who are past Bice Award recipients.

We are proud of you, Greg. Thank you for everything you've done for us!
